  1. AKnight

    This is the best bed frame for the priceI assembled my own DIY king size mattress about 12 months ago, replacing a hand me down queen that we’ve had for 10+ years. I didn’t have a frame so it’s just been on the floor.Every time I would shop for a frame on Amazon, I would get overwhelmed by all the options. Those under $200 look like junk and the expensive ones were out of my price range. I finally stumbled across this one, and after approving it with my girlfriend, went ahead and pulled the trigger.I could not be happier, it’s absolutely perfect for my needs. They recommend that 2 people assemble it, but it was easy enough to do by myself. Feels incredibly sturdy and I am not surprised. The frame is steel, it has good quality hardware and everything locks into place.

    Better than expected.This bed frame is solid, sturdy, and easy to put together (diagram without words format). It’s not super heavy so if we move our bed it’s not a problem. I’d recommend this.

    Solid metal frame with ample storage space.Last year, we gave away an extremely sturdy bed frame to someone who needed it after an injury, and finally the spare we had been using (not sturdy, made of press-board) broke. We wanted something approaching the rock-solid frame I’d had before to replace it (250lb+ guests had no problem or creaking), but decided to go for something with storage space. After extensive review-shopping, we went for this frame in the black, 12″ version. Purely aesthetically, I preferred the look of the lower profile bed I had, but storage was more important here.Average assembly time– had to look twice at the directions and backtrack, make sure you double-check! Overall, worth it, and this one is so far doing just as well (partner and I together are 310lbs), plus has room to store flat totes and small boxes. No creaking ever so far, and it’s seen good, regular use for about 6 months. Imagine that this will last until it changes houses/hands in the future.

    Love it!This took my husband and I about half an hour to assemble! It was very easy to put together! I loved the little adhesive strips on the frame! We got a bunkie board to go with it too. It doesn’t creak at all! Very sturdy for heavy couples!

    Super sturdy bed, especially great for merciless adult adventures, but add some slatsAfter spending way too long on a old box frame that clunked and rattled with every movement, I purchased this platform frame as it appeared to be one of the sturdiest on the market to go with a new mattress I bought. It comes in a big heavy box, and was packaged very well with foam to protect parts, it arrived without a hitch. Assembly is quite easy, only taking about 30 minutes.I did add a dozen 1×3 slats going perpendicular to the metal bars, the metal bars on this are just too thin and spaced too far apart for modern hybrid & foam type mattresses, the way it comes would actually void your mattresses warranty because of the wide spacing. Adds about $50, but well worth it for better support.Pro tip: because of it’s sturdy construction you have metal base all the way around, watch the corners when you are walking around the bed barefoot because if you floss your toes on the bars, you will experience great agony as the solid metal construction is far more durable than your flimsy little toes. You only do that once or twice, and you will learn to be more careful.But it really is a great frame, at this price you aren’t going to find anything more durable. My wife and I can now enjoy a good nights sleep, as well as perform sinful gymnastics on a bed that doesn’t make a peep, nor make you question how much more abuse it will take until it collapses.

    Bought the King Frame after Years of Having the Twin FramesI bought this frame to go in our short-term rental after having the identical twin frames for several years. I wanted to get rid of the dated dust ruffle look. The taller version is almost as high as the box spring we had and it immediately updated the space. I love that it is so easy to clean underneath. It was extremely easy to put together…actually fun. The instructions were perfect. It is also very strong and the mattress seems secure on top.

  7. Amazon Customer

    Nice!!Well made, steady a little low but great for temporarily bed.

  8. ParadoxLive

    Beautiful BedframeThe style is spot on. The quality is exceptional. Assembly is a snap. Only complaint – there’s nothing to hold the mattress in place so I put down the rubbery mesh rug pad/non slip stuff and it’s perfect.

    Very Well Made BedAs others have mentioned, this bed is very well-made. I think it would survive World War III. I bought this because I needed a strong base for my purple mattress. This was the easiest bed I’ve ever had to put together. It took one person about 30 to 45 minutes. My only complaint is the color. It’s sort of a cement metal color. It is dark gray with sort of a brown tint to it. It kind of looks like the metal of file cabinets in an office. It’ll work, I just wish it was more of a lighter silver / grey. Also it would be nice if you could buy a matching headboard for this. Otherwise I’m very happy with my purchase.

    Sturdy and QuietGreat bed, light weight, very sturdy, very quiet. I top 250 lbs so I took some extra care during assembly and used lock-tite on each screw. With a carpet underneath and some tape to keep it still this thing hasn’t moved an inch nor has it squeaked or shaken apart. Highly recommended, would buy again.
